is obtained by dissolving the phtalimidoketone in warm alcoholic 
potash, diluting the solution with water, precipitating with 
hydrochloric acid, and recrystallizing from alcohol. M. P. 165°.

The aminic acid is decomposed on boiling under the reflux 
condenser for an hour with four parts of strong hydrochloric acid into 
phtallic acid, which separates on cooling, and the hydrochloride of 
p--methyl-w-amidoacetophenone, which remains in solution and gives 
colourless needles on evaporation. Recrystallized from alcohol, it 
melts at 206° toa red fluid.

The solution of the salt reduces Fehling’s solution, giving odour 
of pyrazine. With fixed alkali, it gives the free base which at once 
decomposes with production of a red-coloured compound. 
Gold salt is precipitated from its concentrated solution in long 
needles. M.P. 167°.
